Blockchain: What is the use case for physicians in 2024? A rapid review of the literature.

Blockchain is topical in many areas of science. The impact on clinical care of physicians is not known. We undertook a rapid review of the literature to identify areas of interest for clinicians in active practice focusing on evidence relevant to clinical care. We found limited evidence for use blockchain in clinical practice with most studies focusing on technical aspects of prototypes and implementation with no evidence of standardised metric to measure impact for patients, clinicians, and organisations. Personal Health Records for use across organisational and geographic boundaries emerged as the strongest clinical use-case. Defined metrics by professional bodies might aid research, development, and future impact.
